Thanks to a special woven structure, these sliding bearings made of composite material warranty excellent friction properties and improved wear resistance without external lubrication even under high loads.
Product caracteristics:
H-Liner™ M products are manufactured with an homogeneous woven sliding polymer, on the complete wall thickness. Mechanical characteristics are near from brass and don't require any greasing.

Mating shaft:
For optimal performance we recommend to use grinded pin with a roughness lower than Ra 0,4 μm and hardness higher than 400 HB. HEF DURFERRIT PEL™ OX pin are particularly appropriated to work against H-Liner™ bushings.
Advantages
- Maintenance free
- Enable machining of pieces with complex shape
- Low water absorption
- Low weight
- Misalignement resistance properties
Assembly instructions:
H-Liner™ M bearings are best assembled by press fitting or by nitrogen mounting (Other assembly techniques can also be used, ex: glue). For further information, please contact HEF DURFERRIT prior to use.
